Simperium is a new beta product to help developers sync data between
clients and servers. It looks promising because it’s made by the Simplenote
guys who know their stuff, and it integrates seamlessly with Core Data. I don’t
know for certain, but I’d bet that it’s using the incremental store
feature that shipped with Core Data in iOS 5.

I’ve used Simplenote before. It was solid, fast, and it still gets rave reviews
from users today. Given all the iCloud Core Data syncing woes floating around
on Twitter, this tool looks like it could be a good thing to keep in mind.
